my phone has been dying much faster than normal (used to be able to go until night before I needed to charge with moderate use) I now need to charge in the early afternoon, as the battery usually drops below 20% by noon. I have tried everything I can on these forums, battery callibration, cache clear, no background apps. I installed BetterBatteryStats but can't upload screenshots here yet, but the one kernel wakelock that is on the most is "usb" at 92% and "suspend_backoff" at 37%. also shows the CPU at 300mhz 61.7% and 1.2 ghz 30%. (newbie, non-rooted) Please help with any advice!!!
